Electrical connection

To ensure that the radio modem is protected against electrical interference the
housing of the modem must be connected to the ground of the vehicle.
This is, for example, guaranteed when the radio modem is fixed to the conduc-
tive parts of the vehicle using the supplied mounting brackets.
Since the CAN interface of the radio modem is electrically separated the potential
"CAN_GND" of all CAN participants must be linked. Otherwise a safe device
function is not ensured or the CAN interface can be destroyed.
The potential "GND" of the operating voltage must be connected separately.

If required a firmware update can be made by means of the software tool "CAN-
com Downloader" via the serial interface.
For normal operation the serial interface is not needed.
For information about the CANcom software tool please refer to the Internet.

Aerial

(not supplied)
When mounting the aerial(s) in vehicles avoid the vicinity of fuel tanks, vessels
with explosives or insufficiently screened electronic components (see safety
instructions). The aerial should not be installed in enclosed metal constructions
such as driver's cabs (screening Faraday effect).
Do not extend or shorten the cable of the aerial(s)!
Operating the CANcom radio modem
without aerial(s) can destroy the device.
A good aerial signal is the prerequisite for a stable direct online transmission. In
case of problems change the position of the aerials or the mobile equipment if
necessary or contact the ifm support for further possibilities. A loosely tightened
aerial connector also causes signal loss! Please observe the notes of the aerial
manufacturer.
